Maybe your understading of the elcb/ rccb is not true.Any load
consumed current is shared among the phases or and
newtral.that means what ever current that flows through the
elcb must flow out,there can be a difference only when there
is a loss, which means some of this current that had flowed
through are flowing out a different route,(leakage)if this
difference exceeds the trashold of the elcb/rccb than it
trips.

Dear sir, we are getting voltage fluctuations suddenly for 2 or 3 minutes again it becomes normal. we checked each and every connection some times we are getting 110 volts like that from earth to neutral again it is reducing we are getting supply from 45 kva DG set give earthing properly.
